Watch live: Gov. Dayton argues before Minnesota Supreme Court

The legal battle between Gov. Mark Dayton and Republican lawmakers is taking stage in the state's highest court. The Minnesota Supreme Court was set to hear oral arguments Monday in the case surrounding the Democratic governor zeroing out the Legislature's $130 million operating budget. Dayton used a line-item veto to force top Republicans to rework major tax breaks and other measures he signed into law earlier this year.
